The concept project is taken from the meaning of the word Karaj in Nafisi culture, which means a gap in the garment, and the use of this concept is reminiscent of the name of the city itself. The form of the element is divided into two parts with a higher and shorter height, which evokes a gap, and this gap has an entrance part that creates an invitation to enter the element. During the studies and examination of the diagrams related to the project's position, ideas in the form of a matrix were considered. which are: extracting the annual graph of Karaj temperature changes, the output of which has led to the production of an ascending and descending line with failure, and this idea caused the creation of edges and parametric design. Another matrix shows the upward trend of the birth chart, and the output of this matrix is evident in the upward trend and growth of the plan.On the other hand, the matrix extracted from the mountains of Karaj city is in the form of sine waves, which can be seen in the ups and downs of this project.
With regard to Iranian and Eastern architecture, it was tried to use folding architecture in contrast to Western and knocking architecture. The twists and turns of the project made us see fluidity in the design, which has a sense of dynamism and continuity. The rotation of long and short shells refers to an invitation to enter the element and a place to install a park road sign with a good view. By creating a difference in height at the entrance and creating a wave in the entire element, an attempt was made to create a visual diversity of the skyline in the project. Parametricity, fluidity, and curved form all refer to the dynamics of the design, which is related to the subject of the project.
